Answer:

Integral membrane protein that forms channel or protein.

Explanation:

Facilitated diffusion may be defined as the movement of the particles along the concentration gradient of the cell. This type of diffusion is passive process and does not require ATP.

Facilitated diffusion requires special channels or proteins that are made of the integral membrane proteins. These proteins helps in the transport of molecules from the higher region of the concentration to the lower region of concentration.

Thus, the correct answer is integral membrane channel or pores of protein.

Which accurately describes gymnosperms? Check all that apply. Some of them lose their leaves in winter.Some of them lack seeds.S
AleksandrR [38]
I think that correct answers are:
<span>Some of them lose their leaves in winter. (i.e. <span><em>Larix</em></span>)</span>
<span>They include the tallest plants (i.e<em>.Sequoia)

</em>I don't think they are the oldest type of seed plants, since in the past the classes like progymnosperms and seed ferns existed prior to the gymnosperms. But question isn't absolutely clear to me and I can't be 100% sure.
All of the gymnosperms have seeds unless human grows some seedless variant.
Gymnosperms don't have flowers like angiosperms do, but some people think that cone is kind of flower.
Male cones produce pollen, not female.
Hope I helped :)
